Parker 322HB-16N Barbed Tube Union Connector 1 in

Product Description

The PARKER 322HB-16N is a single-barb tube union connector designed to join two lengths of flexible tubing in-line without tools. Molded from nylon, this fitting handles a working pressure up to 125 psi and operates across a temperature range of -40 degrees F to 200 degrees F, making it suitable for a broad range of fluid-transfer applications. The white nylon construction meets FDA compliance and NSF/ANSI 51 standards, confirming suitability for food-equipment environments. It accepts tubing with a 1-inch inside diameter and a 1.08-inch outside diameter on both ends, providing a symmetric, leak-resistant barbed connection. Licensed plumbers, HVAC technicians, and food-service equipment installers are the primary users of this fitting.

This connector is used in residential and light commercial plumbing, food and beverage dispensing equipment, water treatment systems, and HVAC condensate or process-fluid lines where NSF/ANSI 51 food-zone compliance is required. Its single-barb, push-on design suits applications using flexible plastic or rubber tubing rated for the 125 psi working pressure of the fitting. The symmetric union configuration allows in-line splicing or repair of existing tubing runs without specialized tooling.

Installation Notes

Shut off fluid supply and relieve system pressure before removing or installing this fitting. Push tubing firmly over each barb until the tubing seats against the fitting body, and secure with an appropriately rated clamp where required by local plumbing codes. Do not exceed the 125 psi rated working pressure or the 200 degrees F maximum temperature. Installation in potable-water or food-contact systems should conform to applicable local plumbing codes and NSF/ANSI 51 requirements.
